Seebeck coefficient measurement by Kelvin-probe force microscopy [PDF]

, 2009
In order to measure the Seebeck coefficient of nanometer-scale thermoelectric materials, we propose a new technique in which the thermoelectric-motive force (TEMF) is evaluated by Kelvin-probe force microscopy (KFM).

Electron‐Beam Enables Spatially Resolved Defect‐Mediated Work Function Modulation in FAPbI3 Perovskite Thin Films

Advanced Science, EarlyView.
Electron‐beam irradiation enables defect‐mediated work function modulation in metal halide perovskites by regulating interstitial iodides. This approach allows continuous Fermi‐level tuning and spatially resolved formation of lateral surface‐potential‐defined junctions with built‐in potential.

Permanent Oxidative Dipole Engineering in Quinoline COFs for Boosting Exciton Dissociation and Oxygen Activation in H2O2 Photosynthesis

Advanced Science, EarlyView.
Permanent oxidative dipole (POD) engineering overcomes the electronic uniformity of quinoline‐linked COFs. By enhancing the dipole moment to 2.08 D and lowering exciton binding energy to 20.3 meV, it constructs a robust built‐in electric field and spatially decoupled redox centers. This bypasses inherent kinetic bottlenecks, achieving a 4569 µmol g−1 h−

Intergranular corrosion of TiNb-microalloyed martensitic stainless steels processed by quenching and partitioning

Journal of Materials Research and Technology
This study investigates the localised corrosion mechanisms in laboratory-processed Q&P-treated martensitic stainless steels. Two steel variants, one NbTi-free (alloy B) and the other micro-alloyed with Nb and Ti (alloy M) were investigated to elucidate ...

Grain‐Boundary‐Enriched Cocatalyst Coupled With CuSCN Hole Transport Layer for Efficient Solar Water Oxidation in BiVO4 Photoanode

Advanced Science, EarlyView.
A grain‐boundary‐enriched NiFe cocatalyst is coupled with a CuSCN hole transport layer on BiVO4 photoanodes. The integrated architecture promotes hole extraction, interfacial charge transfer, and surface OER kinetics, highlighting cocatalyst microstructure regulation as a complementary strategy to hole transport layer engineering. ABSTRACT Solar‐driven

Self‐Healing Ionogel Dual‐Network Enables Synergistic Defect Passivation and Strain Relief for High‐Efficiency Robust Perovskite Photovoltaics

Advanced Science, EarlyView.
PSCs are afflicted by inherent defects and lattice strain that limit PCE and stability. A cross‐linked multifunctional ionogel [HA‐AA][EMIES] is developed to modulate crystallization, relieve residual strain, and passivate defects, extending carrier diffusion length to over 8 µm and delivering PCEs of 26.45% for rigid devices and 25.14% for flexible ...
